A right triangle is labeled with the hypotenuse 12m and an acute angle 23 degree
. Which of the following equations could be used to find the side length of one of the legs of the triangle.
A) sin. 23=12/x
B)cos =12/x
c)sin 23 =x/12
D) tan 23=x/12

Answer 1

Answer:

sin23=x/12

sin23(12)=x

0.391(12)=x

x=4.7 or 5
